T 0 all whom it may concern:

Be it known that we, CHRISTIAN W. CAMP and JOSEPH E. CAMP, both citizens of the United States, residing, respectively, at Metamora, Woodford county, and Washington, Tazewell county, Illinois, have invented certain new and useful Improvements in Portable Elevators; and we do herebydeclare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates in lportable elevators.

In the device about to be described the ordinary plate form of flight is provided for the conveyer chain with which, at times, a detachable bucket is used, and it is our purpose to provide a mechanism of simple form by which the idler sprocket wheels within the elevator, with which the chain is in connection, can be altered in position so that said chain can accommodate itself to the conditions that exist whether using the said flight or the bucket and this is one of the objects of the invention.

A further object is to make the conto improvements veyer or drag adjustable vertically and longitudinally by which it may be accommodated to the change in position of the said sprockets.

Another object of the invention is to pro-y vide a new arrangement at the place of meeting of the conveyer and the elevator which will automatically accommodate itself to the positions of and follow the tilting movements of the said conveyer and elevator relatively so as to prevent loss of grain at that point, all of which will be fully described hereinafter.

In the drawings presented herewith Figure l is a vertical longitudinal section of part of the elevator and conveyer mounted upon the usual wheeled frame. Fig. 2 is. a plan of the same. Fig. 3 is a side elevation. Fig. 4 is a transverse section of one side of the conveyer and an arm adjusting device secured thereto. Fig. 5 is also a transverse section of one side of the conveyer showing a bracket secured thereto. Fig. 6 is a vertical longitudinal section of part of the elevato-r and conveyer showing buckets iny connection. with the flights ordisuitably mounted upon a wheeled frame' Patented Jan. 9,1912.

A, and B-is the bottom thereof, preferably j of sheet metal. n C is the conveyer or drag usually em'- ployed in connection with the`elevator' andl which also has a sheet metal bottom C The said conveyer is usually pivoted vto the elevator so as to be raised and lo'wered'thereon but in this inst-ance it is done through an f arm D at`-each side of said conveyer the rear ends of which are adjustably secured to said conveyer by means to be described presently. The forward ends of said arms are pivoted to the elevator by,v means of bolts E held in a cast-ing VF secured to each side of theelevator. This casting is in the 'form of a plate slotted at each end at G as shown in Figs. 3 and 9. Bolts H extend through the sides of the elevator and extend through the said slots G, said bolts and slots providing for the adjustment of the plate atright angles to the path of the usual drag-chain to be described presently. Said plate is provided with a hub J which extends inwardly through a' slot K in the side of the elevator as clearly shown in Fig. 9, said `slot admitting of the adjustment just mentioned. Extending fromthe said' hub J is a reduced portion L` for receiving sprocket and prevents lthe ygrain` from interfering therewith.` `This said guard, as shown in Fig. 8, is vprovided with a hole'-v C and 'an inwardly-extending flange P whose face is provided with a series of teeth Q, while the ends'of the" portions L have corresponding teeth R4 as in Fig. 7, one set of ,teeth engaging the other as shown in Fig. 9. The purpose of this is that the guards may be tilted to any de-` sired angle and then fixed in position.

the elevator, as shown: in Fig. 6.

Extending outward from the plates F are hubs F', Fig. 9, against which the arms I) bear. A bore S extends through the said plates and their integral portions through which extends the bolts E above mentioned, said bolts extending also through the ends of the bars D, and receiving the nuts U at their inner ends which bear against the said guards and holds them and the sprockets in place.

In each corner of the elevator and conveyer are preferably placed strips V and V respectively upon which the conveyer chains drag, a portion of one of which chains is indicated at W in Figs. 1 and 2. (See also broken lines in Fig. V6.) In' Figs. 1 and 2 Athe ordinary flights are indicated by the numeral 2V which in the latter `figure are not shown connected with'thev chains. In Fig. 6 the flights are also indicated to which are attached an elevator bucket 3. As in other devices of this class the idler sprockets N described, serve to hold the chains down to position so that the flights will drag upon the bottom. It is desirable to provide a vertical adjustment of 4said idler sprockets. Since in using the 'iights the wheels can be adjusted closer to the' strips V than when employing the buckets. When the latter are employed, by reason of the length of their bottoms they are caused to tilt on striking the inclined bottom of This cramps the chain and consequently tends to shorten its length and raises it against said wheel and wouldcause the entire device to run hard by placing this additional strain thereon, as a matter of course, more power would be needed thanwhen running freely. To provide against this the sprocket is mounted on the movable plate F so that it can be raised whenever the buckets are to be employed and by the, same rule when the buckets are removed the' sprockets are lowered in order that the flights will be held upon the bottom as already stated. The adjustment of the arms D upon the elevator through the movement of the castings F will necessarily impart an adjustment to the conveyer to the required extent and position when said arms are xed in position on the latter. It isl preferable to have the arms pivoted opposite the axes of the sprockets in order that the pivot for the conveyer will be equidistant from all parts of the chain as they-travel on the periphery of said sprockets so that when said conveyer tilted on end the chains will not be tightened to too great an extent. Except for this the arms could be pivoted at other positions found most desirable. In order to permit the arms to shift and allow the conveyer to be held in proper position relative to the elevator some means must be provided for adjusting the arms relative to such con-- veyer. Acasting 4 is bolted to the side of the conveyer by means of bolts 5 being provided with slots 6 tov permit of horizontal adjustment thereof. The top portion of the casting is serrated as shown in Fig. 4 at 7 with which engages the serrated face of a second casting 8 provided preferably ivth flanges 9y at each side between whichV the arm DV lies. A bolt 10 extends through a vertical slot 11 in the casting 4 and also through the casting 9 and the arm I) and' serves to clamp all of these members rigidly together. Secured also to the conveyer is a casting 12 slotted-horizontally at 13 and secured to said conveyer by bolts 14, the end of the bar being attached thereto in suitable manner.

It will be seen that vertical adjustment of the arms can be made by loosening the bolts 10 and shifting the castings 8 upon the castings 4, the said bolts shifting through 'said slots 11.v A horizontal adjustment of the arms relative to the convey er is had through the bolts 5 and 14 and the slots 6 and 13 respectively. The means thus provided allows the operator any adjustment desired to suit the existing circumstances.

It is observed that the sides of the elevator extend downward beyond the end of the bottom B and the strips V thereon and it will be further observed that the ends of the strips of both the elevator and conveyer as well as thefbottom of these latter members are some distance apart, and in order that the flights 2 will properly pass from the conveyer to the elevatorwithout. catching upon the ends of the said strips V of the elevator theplates 15 are provided which are let into ythe strips of the conveyerl flush with their side surfaces, being secured in place in any suitable manner as shown in Figs. 1 and 2, their free ends proj ecting across the space between the bottom to close the recesses between the strips V V .and'extend between those of the elevator substantially as shown.

In order to provide against loss of grain at the juncture of the conveyer and elevator a member 16 is provided which, as shown, in Fig. 10, consists of a plate 16 secured in suitable manner upon a rod 17, lthe ends of the lat-ter being pivotally heldin a pair of arms 18 secured to the sides of the elevator. At one end of the rod 17 is secured an arm 19 to which is attached a spring 20 whose opposite end is connected to the side ofthe elevator in any suitable manner, as shown in Fig. 2. The said rod 17 lies immediately beneath the extremity of the bottom B of the elevator, and said plate 16, due tothe tension of the spring 20 is held close to the bottom of the conveyer and follows the latter in all its movements. Fig. 3 shows how said plate follows the conveyer as it is raised to a substantially vertical position. 130

Since this plate lits snugly between the sides of the elevator there is no chance for grain to be lost. By using the plate a wide range of adjustment of the conveyer in the direction of its length is possible which is often an advantage.

The manner of attaching the buckets to the flights is not shown or described and is not important but it will be observed that in Fig. 6 the bucket which has aback wall and a bottom, is tipped as the forward edge of its said bottom meets the inclined bottom of the elevator and this tends to kink the chain and thus shorten its length as before stated since the flight to which the bucket is secured is tipped Afrom its vertical position. An adjustment of the sprocket N is therefore provided in order that thechains may be loosened when the buckets are employed and to take up the slack Atherein when said buckets are removed. Although the end of the bottoms B presents an edge with which the flights may apparently interfere yet the metal is much thinner than represented in the drawing so that little trouble of this kind will be experienced. n
